| 摘 要： | 利用缝隙系数将钢壳内外各种电流源在壳内产生的磁场分成两部分,一部分按无壳处理,另一部分按无洞无缝的铜壶处理,因而各部分垂直场的解析计算结果与实验值符合很好,并能很好地解释HL-1装置平衡放电长达1S和外加垂直场很小的根本原因。经在装置上关闭内垂直场试验,结果表明,虽然有厚钢壳存在,外垂直场完全可以代替内垂直场。与以前相比,明显地改善了等离子体位置的平衡控制。

| Abstract: | The magnetic field inside the copper shell generated by various currents inside and outside the shell is calculated as a sum of two parts with a gap coefficient of the shell applied. One part corresponds to an arrangement without shell and the other with a complete shell. The calculated magnetic field inside the shell agrees well with the measurement. The fact of a rather long discharge duration time of about one second under a small vertical field applied is explained. The experimental results freom the HL-1 device show that additional outer vertical field coils caa substitute for the inner coils. After this modification, the plasma equillibrium is improved and discharges with low safety factor(1.9) can be reached easily. |
